WebEmergence theory focuses on projecting the 8-dimensional E8 crystal to 4D and 3D. When the fundamental 8D cell of the E8 lattice (a shape with 240 vertices known as the “Gosset polytope”) is projected to 4D, two identical, 4D shapes of different sizes are created. The ratio of their sizes is the golden ratio. WebThe refracted beam acquires some degree of polarization. Most often, the polarization occurs in a plane perpendicular to the surface.
